2. Create a textarea

wysihtml5 takes a textarea and transforms it into a rich text editor. The textarea acts as a fallback for unsupported browsers (eg. IE < 8). Make sure the textarea element has an id, so we can later access it easily from javascript.
The resulting rich text editor will much behave and look like the textarea since behavior (placeholder, autofocus, ...) and css styles will be copied over.

Make sure you place the <script> at the end of the document, before the </body> tag because the document must be loaded before running the script. Or, test if document is loaded (i.e. jQuery's $(document).ready()) and initialize the editor aferwards.
